Motor Speed Control

  1. Oct 20, 2008 #1
    I am interested in designing a motor speed control. I am thinking I would like to use IGBTs as the power transistors, 600V 60A max ratings. I do not have a motor yet. Will it be possible to use a motor rated at a much lower voltage? It will probably be a DC motor in some type of small electric vehicle, and i havent really seen high voltage DC motors.

    What sort of things do I need to consider when the load is drawing much less power than the max rated power of the transistor (efficiency, etc)? Any information on the matter will be helpful. Thanks for any reply.
